GRATING-MACHINE.

Specificationof Letters Patent. Patented Oct. 3, 191 6.

Application filed May 29, 1916. Serial No. 100,648.

To all whom it may concern Be it known that l, Jena BUTERA, a citizen of the United Statcs,,residing at Dallas,

in the county of Dallas and State of Texas, have invented certain new and useful Improvements in (lrating-l\lachines of which the following is a specification.

My invention has relation to a grating machine for cheese. vegetables or similar culinary articles and in such connection it relates more particularly to the arrangement and construction of the parts consituting such a machine.

The main object ot. my presentinvention is to provide a grater for cheese, vegetables or similar culinary articles comprising a grater disk, revolving in a hopper-like frame which is open at the bottom and in connection with such arrangement the disk is provided with teeth or tins offineness or coarsen ess varying from the center of the disk toward its periphery and the hopper is provided with a plurality of supports arranged to constitute a means tor presenting the article to be grated to either the fincr or the coarser tccth oi the disk.

The nature and scope of my invention will he more fully understood from the following description taken in countction with the acemnpairving drawings, forming part hereof. in \vhich- V Figure l. is a. front elcvational vicw. partly broken away. of a grater cmluulving the main features olbm v invention. Fig. is a top-or plan view-of the same. l ig,

' is an cud clcvational view of the grater disk section.

. l' truncated bearings 'i:1 the inclined sides ol the hopper with the hopper or framishown in cross- I Fig. 'l. is a rear vicw of thc grater disk. and Fig. fijis a dctail sectional view illustrating theconnection between thc grater disk and the operating shaft.

llcl crring to thc drawings- 1 represents the l rainc ot the grater constituting a hopper prct craldlv open at oth bottom and top. In gcncial use the frame 1 forms a hopper pyramidal form. 'lhrough is inscrtcd thc shalt I- having a handle -l. The two remova le collars 5 scrve to hold the shaft in the bearing 2. On the shaft 3 is supported a spider or frame-work 6 to which the grater disk 7 is secured in any suitable manner. This disk Tis provided with two series of V-shaped'grater teeth 8 and 9 for relatively line and relatively coarse grating. As shown in the drawings the teeth are punched in and project from the face of. the disk and are arranged in spirals with the liner teeth 8 grouped nearest the periphery of the disk while the coarser teeth 9 are grouped near and around the center of said disk. However this arrangement or groupin may be reversed if desired.

The top of one inclined side of the hopper is cut away to form a space through which the cheese or article to-be grated may beintroduccd against the grater disk 7. Atthe ends of the frame work 1 adjacent; to this open space arc secured the eleatslfl fi'rranged upp erbimrd or'rest ll 'dm'ingthe grating operation. but when 'it isto'be grated into relatively coarse particles the material is supported on the lower boarder rest after thc upper board or rest has been removed.

The preferred means for securing the spider or frame U to shaft 2 is illustrated in the detail in Fig. 5. it c nsists of a tube 12 rcmovably secured to the shaft 3 and hating screw threaded ends. i

The spider t' is clamped to this sleeve or tube l2 by means of the nuts 13 which are advanced on the screw threaded sleeves to tightly clamp the spider to the sleeve llavingthus described the nature and Olijccts of my invention what I claim as new and desire to secure h v Letters Patent. is

l. in a device of the character described, a rcvoluldc gratcrdisk having grating tins .of V-shape and punched in and projecting from its face in spirals. said tins varying lll.

sizc and a rrauged in concentric sets whereof one set is grouped about the ccntcr ot the disk and -thc other adjacent to the periphery thc rcol 2. In a device of the character described,

a revoluble grater disk having grating fins posed boards detachably supported at varypunched in and projecting from its face in ing points in said hopper adjacent to the spirals to form two concentric sets of varydisk to constitute supports for the articles 19 ing size and fineness, one set grouped about to be grated. 5
